If you are a developer from programming languages such as Java, Python, C++, C#, you should feel familiar with the object-oriented style of coding. However, if you are not familiar with any other object-oriented programming languages, you will probably be puzzled by this term, as it sounds a bit abstract. However, don't worry; this is much easier to understand than it looks if we think about the core of programming.
When we talk about programming, we are actually talking about using programming tools to solve problems. Before solving the problem, we need to model the problem first. Traditionally, we usually figured out an algorithm that takes several steps to solve a numeric computing problem. Then, we wrote some procedural code to implement the algorithm. For example, most statistical algorithms are implemented in a procedural style, that is, by transforming the input into the output according to the theory, step by step.
However, many problems are...
